Method Detail

addVertex

Point2D addVertex(double x,
                  double y)

Adds a vertex at the end of the list.

Parameters:

x - The X location of the vertex

y - The y location of the vertex

Returns:

A Point2D object with the location of the vertex.

getVertex

Point2D getVertex(int index)

Parameters:

index - The index of the vertex in this list to get.

Returns:

The vertex.

getVertexCount

int getVertexCount()

Gets the number of vertices that are held in this object.

Returns:

The number of vertices.

removeVertex

void removeVertex(int index)

Removes a vertex from this list.

Parameters:

index - The index of the vertex to remove.

isModified

boolean isModified()

Returns a flag indicating whether the list of vertices, or any vertices in the list has been modified.

Returns:

Flag indicating if this list has been modified.

setModified

void setModified(boolean mod)

Sets the modified flag.

Parameters:

mod - The new value of the modified flag.
